Instructions:
  • Answer 50 questions in 15 minutes.
  • If you are not ready to take this test, you can study here.
  • Match each statement with the correct term.
  • Don't refresh. All questions and answers are randomly picked and ordered every time you load a test.

This is a study tool. The 3 wrong answers for each question are randomly chosen from answers to other questions. So, you might find at times the answers obvious, but you will see it re-enforces your understanding as you take the test each time.
1. The distal sesamoid bone of the horse; located deep in the hoof behind the joint between the middle and distal phalanges.






2. One of two bones (the radius is the other) that form the antebrachium - or forearm; forms a major portion of the elbow joint with the distal end of the humerus.






3. Mature bone cells located in lacunae.






4. Paired sesamoid bones in the legs of horses; located in the large digital flexor tendons behind the fetlock joints.






5. Large process of the fibular tarsal bone that projects upward and backward; commonly referred to as the point of the hock. Site of attachment of the gastrocnemius (calf) muscle and equivalent to the human heel.






6. The microscopic - laminated cylinders of bone that make up compact bone. Oriented lengthwise in a long bone - these consist of a central haversian canal surrounded by concentric layers of bone. Osteocytes in their lacunae are present at the junctions






7. The mineralization or hardening of bone.






8. The central canal that runs the length of a haversian system; contains blood vessels - lymph vessels - and nerves that supply and nourish the osteocytes.






9. Skull bones; external bones of the face. These two bones make up most of the upper jaw and house the upper canine teeth - if present - and all of the cheek teeth.






10. The bony roof of the mouth; the division between the mouth and the nasal cavity. Made up of portions of the maxillary and palatine bones.






11. The membrane that encloses the ends of the bones in a synovial joint; consists of an outer fibrous membrane and an inner synovial membrane that produces viscous synovial fluid that lubricates the joint surfaces.






12. The first cervical vertebra; it forms the atlantooccipital joint with the occipital bone of the skull and the atlantoaxial joint with the axis.






13. A spheroidal articular surface on the proximal end of a long bone; present on the proximal ends of the humerus - femur - and rib. Joined to the shaft of the bone by an area that is often narrowed and called the neck.






14. Skull bones that are part of the external bones of the face; form the bridge of the nose or the dorsal part of the nasal cavity.






15. Long bones of the axial skeleton that form the lateral walls of the thorax; dorsal portions are made of bone and form synovial joints with the thoracic vertebrae. Ventral portions are cartilage.






16. The smooth joint surface of a bone that contacts another bone in a synovial joint.






17. The lay term for the most proximal joint of the equine digit - which is the joint between the large metacarpal or metatarsal and the proximal phalanx. The proximal sesamoid bones are located on the caudal surface of this joint.






18. The vertical portion of the mandible located at its caudal end; site where jaw muscles attach to the mandible.






19. An immovable joint; also known as a synarthrosis. The bones are firmly united by fibrous tissue; includes the sutures between the skull bones.






20. A joint motion whereby the distal end of an extremity moves in a circle.






21. The bones of the limbs (appendages)






22. The bony canal in the temporal bone that leads into the middle and inner ear cavities of the bone; in the living animal - it contains the external ear canal.






23. Bones of the forelimb that lie between the carpals and phalanges of quadrupeds.






24. A skull bone; one of the external bones of the face. It is the lower jaw - the only movable skull bone - and contains all of the lower teeth.






25. The socket portion of the ball - and - socket hip joint; it is formed at the junction of the ilium - ischium - and pubic bones of the pelvis.






26. The junction between two bones; can be completely immovable (fibrous) - slightly movable (cartilaginous) or freely movable (synovial).






27. The long bone of the brachium or upper arm.






28. Blood cell production; usually occurs in red bone marrow.






29. One of two small sesamoid bones located in the proximal gastrocnemius muscle tendon just above and behind the femoral condyles of dogs and cats.






30. An immovable fibrous joint - such as the suture that unites most of the skull bones.






31. Skull bones that are external bones of the cranium; form the lateral walls of the cranium - contain the middle and inner ear structures - and are the skull bones that form the temporomandibular joints with the mandible.






32. Viscous fluid formed by the lining layer of the joint capsule of a synovial joint; lubricates joint surfaces.






33. The smallest and most medial of the three pairs of bones that make up the pelvis; forms the cranial portion of the floor of the pelvis.






34. A large - rounded articular (joint) surface; examples are found on the distal ends of the humerus and femur.






35. The visceral bone in the penis of dogs that partially surrounds the penile portion of the urethra.






36. The immovable fibrous joints that unite most of the skull bones; also known as synarthroses.






37. One of the three ossicles in the middle ear; also called the stirrup - it is attached to the oval window of the cochlea and is the innermost of the three ossicles.






38. A toe made up of two or three boens called phalanges.






39. A thin bone located beside the tibia in the lower leg region of the pelvic limb. It is a complete bone in the dog and cat - but only the proximal and distal ends are present in horses and cattle. It doesn't support any appreciable weight - but acts a






40. The most caudal of the three pairs of bones that make up the pelvis.






41. The 'forearm' region of the thoracic limb.






42. The bones of the tail portion of the spinal column.






43. The fibrous membrane that covers the outsides of bones except for their articular surfaces.






44. The thin layer of hyaline cartilage that covers the articular surfaces of long bones in synovial joints; it forms a smooth layer over the joint surfaces of the bones - which decreases friction and allows free joint movement.






45. Bony arches below and behind the eyes of common domestic animals; in dogs and cats they form the widest part of the skull. Made up of the rostral - facing zygomatic process of the temporal bone joined with the caudal - facing temporal process of the






46. A bone of a digit (finger or toe). Pl. - phalanges.






47. The vertebrae of the pelvic region; fuse to form a solid structure which forms a joint with the ilium called the sacroiliac joint.






48. The large process on the proximal end of the ulna that forms the point of the elbow; the site where the triceps brachii tendon attaches.






49. One of the three ossicles in the middle ear; also called the anvil - this bone is the middle of the three ossicles.






50. Long - faced. Example: Collie.
